praying in Notre Dame de Paris 04

Notre Dame de Paris (French for Our Lady of Paris), also known as Notre Dame Cathedral, is a Gothic, Catholic cathedral on the eastern half of the Île de la Cité in the fourth arrondissement of Paris, France. Notre Dame de Paris is widely considered one of the finest examples of French Gothic architecture in France and in Europe. It was restored and saved from destruction by Eugène Viollet-le-Duc, one of France's most famous architects. Notre Dame de Paris was one of the first Gothic cathedrals, and its construction spanned the Gothic period. Its sculptures and stained glass show the heavy influence of naturalism, unlike that of earlier Romanesque architecture.

Notre Dame de Paris was among the first buildings in the world to use the flying buttress (arched exterior supports). The building was not originally designed to include the flying buttresses around the choir and nave. After the construction began and the thinner walls (popularized in the Gothic style) grew ever higher, stress fractures began to occur as the walls pushed outward. In response, the cathedral's architects built supports around the outside walls, and later additions continued the pattern.

The cathedral suffered desecration during the radical phase of the French Revolution in the 1790s, when much of its religious imagery was damaged or destroyed. During the 19th century, an extensive restoration project was completed, returning the cathedral to its previous state.
